Fluidized Bed Powder Coating,Hot Dipping Powder Coating

Kuputira hupfu hwemubhedha hwakanyorova ipurasitiki inoputira hupfu inoiswa nesystem yemubhedha wakanyorova apo zvidimbu zveupfu zvakakuyiwa zvakanaka zvinosungirirwa mumhepo, uye chikamu chakapiswa chinonyikwa mutangi reupfu. Zvikamu zvakanyungudutswa zvinobatana nechinhu chacho, zvichipa kupedzisa kwakafanana, kwakaenzana pazvikamu zvesimbi. Nzira iyi inonyanya kukodzera sepurasitiki inoshanda kuti ipe kukwesha, ngura, uye kudzivirira makemikari. Ukobvu hwenzira iyi i200-2000μm, asi ukobvu hwakanyanya hunogona kuwanikwa.

Icho chikamu chiri cheupfu chakaputirwa ne fluidized bed coating chinoenda nematanho anotevera.

1.Preheat

Chikamu chesimbi chinofanira kupiswa muovheni kusvika 220-400 ℃. Iyi tembiricha yakakwira kupfuura nzvimbo yekunyungudika yehupfu hwemubhedha, uye ita kuti hupfu hunodzima kana kutonhora chikamu ipapo ipapo.

2. Kunyudza

Mufuridziro wemhepo uri pasi petangi rehupfu unofuridza zvidimbu zvehupfu kuita semvura. Isu tinonyudza chikamu chinopisa mumubhedha wakasvibiswa wehupfu hwehupfu uye unofamba uchitenderera kuti urambe uchiputira. Kukora kwekupedzisira kwechishandiso kunoenderana nekupisa kwezvikamu zvisati zvanyikwa mutangi uye kuti inogara kwenguva yakareba sei mumubhedha wemvura wepoda yekupotera.

4.Post-kupisa kurapa

Nhanho yekupedzisira yemvura yemubhedha poda yekuputira ndiyo yekupedzisira kusanganisa maitiro. Mushure mekunge hupfu yakawandisa yadonha kubva pachigadzirwa, inoenda kuchoto pane yakaderera tembiricha kuti irapwe. Iko-kupisa kwemashure kunofanira kunge kune kutonhora kwakadzika kudarika kwevheni yakatsva. Chinangwa chedanho iri ndechekuita chokwadi chekuti hupfu hwese hwakanamatira kune chikamu panguva yekunyura uye inonyungudika kuita yakatsetseka, yunifomu yekupfeka.

5.Kutonhorera

Iye zvino fambisa iyo yakavharwa workpiece kubva muchoto uye itonhodze nemhepo feni kana mhepo chaiyo.

Kufukidza hupfu hwemubhedha hwakanyorova kunosanganisira kunyudza chitofu chinopisa mutangi rehupfu, zvichiita kuti hupfu hunyunguduke pachikamu chacho uye hugadzire firimu, uye zvichizopa nguva yakakwana nekupisa kuti firimu iri ripinde mupurasitiki inoenderera mberi. Chitofu chinofanira kunyudzwa mumubhedha wakanyorova nekukurumidza mushure mekuchibvisa muovheni yekupisa kuti kupisa kusanyanya kuderera. Nguva inofanira kurongwa kuti nguva iyi irambe yakafanana. Paunenge uri muhupfu, chitofu chinofanira kuramba chichifamba kuti hupfu hurambe huchifamba pamusoro pechikamu chinopisa. Kufamba kwechikamu chakati kunoenderana nemamiriro acho.

Kufamba kusina kunaka kana kusakwana kunogona kukonzera matambudziko akati wandei: mapiniko, kunyanya nechepasi penzvimbo dzakati sandara dzakati sandarara uye pamharadzano dzewaya: kutaridzika kweganda reorenji; uye kusavharika kwakakwana kwemakona kana mitswe. Kufamba kwakashata zvakare kunogona kutungamirira kune nonnuniform coating ukobvu, senge oval coating pawaya dzakatenderera. Nguva yakajairika yekunyudzwa muhupfu yakanyungudutswa ndeye masekonzi matatu kusvika makumi maviri.

Yakawandisa poda inofanira kubviswa pakarepo mushure mekuputira kudzivirira kuwanda kwakawanda. Izvi zvinogona kuitwa nekuputika kwemhepo kubva kune yakadzorwa mhepo jet, kurova kana kuzunguza chikamu, kana kuitetemesa kuti irase iyo yakawandisa. Kana iyo yakawandisa poda isina kusvibiswa nehumwe hupfu kana tsvina, inogona kushandiswa zvakare. Kana chikamu chacho chiine kupisa kwakakwana kwakasara, kuvhara kunogona kuyerera kunze kune mazinga anogamuchirwa pasina kupisa kwemashure. Pazvikamu zvakatetepa, kana zvikamu zvinopisa kupisa, posvo inopisa inogona kudiwa.
